Abstract: front page image
(EN)Buffer compositions comprising semiconductive oxide particles and at least one of (a) a fluorinated acid polymer and (b) a semiconductive polymer doped with a fluorinated acid polymer are provided. Semiconductive oxide particles include metal oxides and bimetallic oxides. Acid polymers are derived from monomers or comonomers of polyolefins, polyacrylates, polymethacrylates, polyimides, polyamides, polyaramids, polyacrylamides, polystyrenes. The polymer backbone, side chains, pendant groups or combinations thereof may be fluorinated or highly fluorinated. Semiconductive polymers include polymers or copolymers derived from thiophenes, pyrroles, anilines, and polycyclic heteroaromatics. Methods for preparing buffer compositions are also provided.
(FR)L'invention concerne des compositions tampons contenant des particules d'oxyde semiconductrices et au moins (a) un polymère d'acide fluoré et (b) un polymère semiconducteur dopé d'un polymère d'acide fluoré. Les particules d'oxyde semiconductrices contiennent des oxydes métalliques et des oxydes bimétalliques. Les polymères d'acide sont dérivés de monomères ou de comonomères de polyoléfines, de polyacrylates, de polyméthacrylates, de polyimides, de polyamides, de polyaramides, de polyacrylamides, de polystyrènes. Le squelette du polymère, les chaînes latérales, les groupes pendants ou les combinaisons de ceux-ci peuvent être fluorés ou hautement fluorés. Les polymères semiconducteurs contiennent des polymères ou des copolymères dérivés de thiophènes, de pyrroles, d'anilines, et des groupes hétéroaromatiques polycycliques. L'invention concerne enfin des procédés de préparation de compositions tampons.
